Boss timing info was pulled from logs, 20-man heroic. DPS need to run a bit to soak burning pitch, ranged sometimes need to run with an orb, melee need to run from falling bridgez.
MELEE: currently this will have slightly lower dps than in reality because some APLs need optimization for the extra movement from bridge breaks. We are working on those updates, or you can do them yourself via the wiki editor.
